Additional file 2.

Phylogenetic trees for T. oceanica LGT candidate genes. The file comprises 254 unrooted, Newick-formatted trees containing candidate LGT
genes as described in the main manuscript. Trees and corresponding support values
were generated using FastTree. Novel T. oceanica genes are identified in the trees by a reference number followed by '_TO'. Homologs
from the 'nr' database identified using BLAST are given in the form 'Genus_GI', except
for matches to unnamed genera, which are shown as RefSeq GI number followed by 'X'.
Visual inspection of trees was performed by importing this file into FigTree (Andrew
Rambaut 2007) and assigning a root as described in the Supplementary Methods in Additional
file 3. The file is in .tre format (compressed to .gz).
